General Description
The IDT8N3S271 is a Frequency-Programmable Crystal Oscillator
with very flexible frequency programming capabilities. The device
uses IDT’s fourth generation FemtoClock® NG technology for an
optimum of high clock frequency and low phase noise performance.
The device accepts 2.5V or 3.3V supply and is packaged in a small,
lead-free (RoHS 6) 6-lead ceramic 5mm x 7mm x 1.55mm package.
The device can be factory programmed to any frequency in the range
from 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz and
supports a very high degree of frequency precision of 218Hz or
better. The extended temperature range supports wireless
infrastructure, telecommunication and networking end equipment
requirements.
